Abstract
The invention relates to compositions and methods of treatment employing compositions including a cationic polyelectrolyte, without any anionic polyelectrolytes, so that no polyelectrolyte complex (PEC) is formed. In addition to not forming PECs, and being free of anionic water-soluble polymers (i.e., an anionic polyelectrolyte polymer that could form a PEC with the cationic polyelectrolyte), the composition is also free of random copolymers, block copolymers, coacervates, precipitates, and silicone copolymers. The composition may be a concentrate, to be diluted prior to use to treat a surface.
Claims
exact text as granted — not AI-modifiedThe invention claimed is:
1. A composition consisting of:
(a) a homopolymer of diallyl dimethyl ammonium chloride (“DADMAC”);
(b) 6.6% to 10.5% of an oxidant selected from the group consisting of a hypohalous acid, a hypohalite, and mixtures thereof;
(c) water; and
(d) optionally, an adjuvant selected from the group consisting of a fragrance, a hydrotrope, a colorant, a dye, a buffer, a chelating agent, an electrolyte, an anti-microbial agent, a solvent, a stain and soil repellent, a lubricant, an odor control agent, a perfume, a fragrance release agent, an acid, a base, a solubilizing material, a stabilizer, an anti-corrosion agent, a thickener, a defoamer, a cloud-point modifier, a preservative, a water immiscible solvent, an enzyme, and mixtures thereof; wherein
(e) the composition is free of anionic water-soluble polymers, random copolymers, block copolymers, coacervates, precipitates, and silicone copolymers;
(f) the composition does not form a polyelectrolyte complex; and
(g) the pH is between 11.6 and 12.2.
2. The composition of claim 1 , wherein the composition comprises a base.
3. The composition of claim 1 , wherein the composition comprises a buffer.
4. The composition of claim 1 , wherein the composition comprises a fragrance.
5. The composition of claim 1 , wherein the composition comprises a hydrotrope.
6. The composition of claim 1 , wherein the composition comprises a chelating agent.
7. The composition of claim 1 , wherein the composition comprises an anti-corrosion agent.
8. The composition of claim 1 , wherein the composition comprises a thickener.
9. The composition of claim 1 , wherein the composition comprises a colorant.Cited by (0)
